Lestes that it inhabits Kinki area are Lestes sponsa , Lestes temporalis and
Lestes japonicus.
The inhabiting environment of Lestes sponsa and Lestes japonicus looks alike.
Some egg-parasitoids wasp parasitizes two species of Lestes sponsa and Lestes japonicus

This
egg-parasitoids wasp seems to be distributed widely. This
egg-parasitoid parasitizes both species of Lestes sponsa and Lestes
japonicus.
The egg-parasitoids wasp of the figure parasitized the egg of Lestes japonicus. This
plant is Scirpus triqueter L. There is the egg of Lestes sponsa in
this plant. The length of this female is about 1.20 mm. A white arrow in the figure shows an ovipositor.

Figure1-3: The
male which emerged is waiting for the female which happens that it passes by.
A male rides on the female and copulates. Copulation continuous time is several
seconds.

Figure1-4: This
egg-parasitoids wasp parasitized the egg of Lestes japonicus.

head is yellow. 2. ♀ A female head is blackish.

Figure1-6: Fore
wing is big. Rear wing is small. (This photograph expands into two times of
other photographs.)

Figure1-7: 1. The larva of
egg-parasitoids wasp grows up in the egg. A larva breaks an egg
after that, and goes to the outside of the egg. Then, it becomes a pupa in
the suitable gap of the plant organization. A plant is bitten, and a hole
is made, and this egg-parasitoids wasp comes out. (a.
